Hey DIYers and pros, this Kapro 446 Rafter Square is a real workhorse. It's a 12-inch square made from solid aluminum, and the whole thing is anodized. That means it's super tough, resists corrosion, and won't wear out like cheaper painted ones. The markings are laser etched, so they're crazy clear and they won't rub off over time. On the back, there's a handy conversion table and a 0°-90° protractor scale built right in—super useful for quick layout work. It's got a compact, lightweight profile that's easy to carry in your tool belt. Whether you're framing a roof (that's the 'rafter' part), doing trim work, or just need a super accurate square for all sorts of projects, this thing is a reliable choice. Kapro makes good stuff, and this square is no exception. It's the kind of tool you buy once and use for years.
